Why Students Love CK-12!
Take a look at what these students have to say about CK-12!
Wonderfull! like that it’s really to the point and precise. There’s lots of pictures and diagrams that are helpful when you are trying to learn.
My teacher made these textbooks, and it has everything that we need for this specific class.
It’s really accessible so it’s easy for the whole class to get on and we just go!
We use it every day because there’s something new that our teacher wants us to look at!
My CK-12 book is really nice because it has all of the information I need in it. Instead of hunting for all of the words and questions I have, it’s all there right in order
Comments from Students
In a lot of science, CK12 helped me start off my knowledge in science so I could build off that foundation. It has helped me in many various science subjects, from the EM scale to how rocks are formed. And it isn't ever difficult to understand or condescending and easy. And my grade in science is an A. So thank you, CK12!

In many instances, available resources are not sufficient to explain a particular problem, so it is a relief to be able to turn to cK-12 for help.

CK-12 helps out on 2 of my subjects and it makes learning easy. And, some of the videos are funny and it makes learning fun too. I love CK-12 because I met some people who work for it and they were so nice. CK-12 is awesome, and I think it should never be

My class and I have a new assignment to do and we use cK-12 because it makes us do different things on it to provide us and them with different information they need.
Billy S.
CK12 was a great resource for my middle school students because they were preloaded on their devices. Our internet connections were spotty at best in my classroom and CK12 provided a stable platform for me to teach and students to learn.
Jennifer
It's easy to create assignments for my students and I love that they don't discriminate the fact that I homeschool my children and use this.I hope in the future they have more english to use.Thank you.
Laurisa N.
Ck-12 has brought science to life in my classroom with online videos, challenging reading and built in assessments to help my students know what they are learning.
Courtney M.
CK12.org has given me an online text and teaching materials that are NGSS aligned. This has enabled me to teach to the standards even though our school does not have a physical textbook. This has been such a lifesaver as a junior high science teacher!

We use cK-12 for our high school Science and math curriculums and the students love and the teachers find it easy to use and an enhancement over traditional textbooks.

It is a great multimedia resource that students like to use collaboratively and independently.
